With the artist on probation for throwing eggs at his neighbor's house in January, it's conceivable that cops could take these complaints to the District Attorney and Bieber could be put in jail for violating said probation.

Police, however, cannot make a misdemeanor arrest unless they witness the illegal incident. Hence the possibility of others in the building doing it themselves.

Bieber, of course, has never gotten along well with his neighbors. He memorably (allegedly, we suppose) spit in one's face last year, while his speeding around his former Calabasas hood made him very unpopular with locals.

The star has since moved... but he's clearly taken his irresponsible behavior with him.
